1 1 Emission Standards for SI Marine Engines Mike Samulski Office of Transportation and Air Quality International Boat Builders’ Exhibition & Conference EMD Meeting October 6, 2008

2 2 Outline Overview of new standards Spark-ignition marine engine categories Program details Not-to-exceed zone Small businesses Evaporative emissions Certification Questions

3 3 Final Rule On September 4, 2008, EPA Administrator Steve Johnson signed, into law, new exhaust and evaporative emission standards for spark-ignition marine engines and vessels. These standards apply only to new engines and vessels sold for use in the United States. The standards will help reduce harmful health effects of ozone and carbon monoxide from these products.

4 4 Final Standards: Overview HC+NOx exhaust emission standards for SI marine engines are similar in stringency to existing standards in California New CO exhaust emission standards for all SI marine engines New Not-to-Exceed provisions New evaporative emission standards

5 5 Engine Categories SI Marine Outboards/PWC Sterndrive/Inboards –Jetboats –High performance –Air boats Marine generators Small SI as well

6 6 Program Details Generator Sets OB/PWC Engines NTE zone SD/I Engines Jetboats High performance Small business provisions Evaporative Certification

7 7 Same HC+NOx standards as CARB 2008 Can be achieved with existing technology –2-stroke direct injection engines –4-stroke engines Will essentially phase-out carbureted 2- stroke engines Outboards/PWC PollutantMaximum Power (P) Standard [g/kW-hr] Model Year HC+NOx≤ 4.3 kW > 4.3 kW × ( /P 0.9 ) 2010 CO≤ 40 kW > 40 kW 500 – 5.0 × P

8 8 OB/PWC Standards

9 9 SD/I Standards Similar stringency as CARB 2008 standards –CO standard based on observed performance Catalytic control for most engines Credit program for jet boats using PWC engines Engine-based standards for high-performance engines

10 10 SD/I Standards Maximum PowerHC+NOx [g/kW-hr] CO [g/kW-hr] Model Year ≤ 373 kW a b High performance engines c ≤ 485 kW High performance engines c > 485 kW a This category also includes engines >373 kW that do not otherwise meet the definition of “high-performance.” b 2011 for small-businesses and for engines built using the 4.3L or 8.1L GM engine blocks. c For small businesses, the 2010 standards do not apply and the 2011 standards are delayed until 2013.

11 11 SD/I Provisions Many similar provisions as for OB/PWC –Averaging, banking, and trading –Closed crankcase –Emissions related warranty –Similar test procedures Some differences –Onboard diagnostics –No production line testing –No manufacturer run in-use test program

12 12 GM Engine Blocks Vast majority of SD/I marine engines built from GM engine blocks Planned product line changes –Replace 4.3L with 4.1L –Replace 8.1L with supercharged 6.0L Providing an additional year of lead time for SD/I engines built from these blocks Vortec 8100 Vortec 4300

13 13 High Performance Engines Short useful life and warranty periods No NTE standards Most manufacturers eligible for small business provisions Assigned emission factors 15% torque at idle during test Simplified testing

14 14 Marine Generator Sets Remain classified as small SI engines Stringent CO standard based on new catalyst- equipped marine generators Engine Category SizeHC+NOx [g/kW-hr] CO [g/kW-hr] Model Year Generator Sets ≤ 19 kW < 225 cc > 225 cc

15 15 Off-Cycle Engine Operation

16 16 Not-To-Exceed Standards NTE standards are a multiplier times the E4 duty cycle certification value Catalyst Equipped Engines

17 17 Not-To-Exceed Standards NTE standards are a multiplier times the E4 duty cycle certification value 4-Stroke (non-catalyst) Engines

18 18 Not-To-Exceed Standards NTE standards are a multiplier times the E4 duty cycle certification value 2-Stroke Engines

19 19 Small Business Provisions Broad engine families for high performance Additional lead time for SD/I Early ABT bonus credits for SD/I No production line testing Assigned deterioration factors Economic hardship relief

20 20 Evaporative Emissions Portable tanks –Tank permeation –Self-sealing vent Vessels –Hose and tank permeation –Diurnal emissions –Refueling spillage Engines –Standards apply to hose & tanks directly mounted on engines 309 Boat Fuel Systems: Design and Compliance

21 21 Certification Procedures The ABCs of getting a Certificate of Conformity with EPA emission regulations…

22 22 Certification Procedures The basics: –If your product is subject to EPA emissions standards, you must obtain a Certificate of Conformity before you introduce it into US Commerce. Must demonstrate compliance with the applicable regulation. –Certificates are issued by the Compliance and Innovative Solutions Division (CISD), Office of Transportation and Air Quality. CISD’s Heavy-Duty and Nonroad Engines Group processes the Applications for Certification for Marine SI –You must certify every model year or production period

23 23 How do I certify? To obtain a Certificate of Conformity: 1.Read the regulations! SD/I & components: 40 CFR Parts 1045, 1060, 1065 and 1068 OB/PWC: add 40 CFR Part Request an EPA Manufacturer Code: Contact: Mr. Pete Petersen, ; 3.Determine: Engine Families/Permeation Families The type of Certificate you need: –Exhaust, Evaporative (fuel lines, fuel tanks), or both

24 24 How do I certify? 4.Gather your data 5.Pay your fee: Per Application Information: Pay electronically at: https://www.pay.gov/ https://www.pay.gov/ Contact: Mr. Bill Vanden Broek ov *The amount of the fee depends on the calendar year in which the application is submitted, not the engine’s model year. Pay a fee for each application. Type of Certificate Calendar Year* Use Form Exhaust$694$ Evaporative$241 "Miscellaneous Payments"

25 25 How do I certify? 5.Complete an Application for Certification –Per engine or permeation family –Download application template: epa.gov/otaq/certdat2.htm epa.gov/otaq/certdat2.htm –Software required: FileMaker Pro (versions 7.0 to 9.0) –www.filemaker.comwww.filemaker.com –Questions on completing/ submitting the application: Exhaust: Mike Marko, ; Evaporative: Nick Flores: ; –Carry over, running changes, carry across –Mark CBI –Comments section Application for marine SI components is not on the website yet. Look for it here in the near future. Additional Information

26 26 How do I certify? Engine Family Names –12-character string –Must follow EPA’s family naming convention –MY 2009 = 9; 2010 = A Marine SI (Exhaust) Evaporative (for MY 2009 only) Model Year EPA Mfr Code Industry Sector Code for Fuel Tanks Sequence Characters (Unique Identifier) 9XYZPLINEAB1 Industry Sector Code for Fuel Lines 9XYZPTANKAB1 Model Year 9XYZM1.72AB1 EPA Mfr Code Industry Sector Code for Marine SI Engines Engine Displacement (in Liters or Cubic Inches) Sequence Characters

27 27 How do I certify? Example of Engine (Exhaust) Certification Template. Does not include SD/I yet.

28 28 How do I certify? Not applicable for Marine SI fuel lines. Use measured emission levels for certification. This template will be used for both Marine SI and Small SI components.

29 29 How do I certify? This template will be used for both Marine SI and Small SI components.

30 30 How do I certify? 5.Submit your application –Complete application = template + signed Statement of Compliance –To submit: complete application to: –Subject line: MSI-Company name-# of submissions & Process Code »Example: “MSI-BuyMyBoat-3 new submissions” –One industry and process code per May submit by mail –Allow at least 60 days from the time EPA receives a complete application for processing

31 31 EPA Review Mike Marko or Nick Flores receive the applications and check them for completeness –Contact them if you have questions about the templates or need to know where your cert is If you have a question about Marine SI regulations, contact: Nydia Yanira Reyes ( – Send special requests to: –Ms. Khesha Jennings, Manager, Heavy-Duty and Nonroad Engines Group

32 32 EPA Review Please keep in mind that once you certify, you must comply with all parts of the regulation(s) that apply to your product, such as: –Labeling Requirements –Average, Banking and Trading (AB&T) –Production-line Testing (PLT) –In-use Testing –Warranties –Defect Reports & Recalls –Owner’s Manual requirements –Selective Enforcement Audits –Recordkeeping, etc
